In this tutorial we will be creating the road. Although there are several ways of doing this, I created three functions.
One function for the blacktop part, one for the 2 yellow lines, and one for the white dotted line
Down in the game loop I called the functions to blit the road
Now our car.py should look something like
Which gives us this screen
In the next tutorial we will create the player and mobs
One function for the blacktop part, one for the 2 yellow lines, and one for the white dotted line
Python:
# define a function to draw the yellow lines
def line(surf, x):
line = pygame.Surface((2, 720))
line.fill('yellow')
surf.blit(line, (x, 0))
# Define a function to draw the dotted white line
def line2(surf, x):
line = pygame.Surface((2, 20))
line.fill('white')
for i in range(720):
if i % 10 == 0:
surf.blit(line,(x, i*10))
# Define a function to draw the road
def road(screen):
surf = pygame.Surface((300, 720))
surf.fill('black')
screen.blit(surf, (490,0))Down in the game loop I called the functions to blit the road
Python:
# Blit the road
road(screen)
line(screen, 493)
line(screen, 785)
line2(screen, 640)Now our car.py should look something like
Python:
# Do the imports
import pygame
import os
'''
Get the path of the working directory
Should get the correct path in console or editor
We will use this to access directories containing
images and sound
'''
path = os.path.realpath(os.path.dirname(__file__))
'''
Initiate pygame to acces all classes and functions
'''
pygame.init()
'''
Setup the pygame time clock.
We will use this to set the framerate
'''
clock = pygame.time.Clock()
# Set the framerate
fps = 60
'''
Setup our screen window. A tuple is needed for setting width and height
I'm going to use a 1280 width and 720 height
'''
screen_size = (1280, 720)
screen = pygame.display.set_mode(screen_size)
# Set the caption for the window
pygame.display.set_caption('Dodge Car')
# define a function to draw the yellow lines
def line(surf, x):
line = pygame.Surface((2, 720))
line.fill('yellow')
surf.blit(line, (x, 0))
# Define a function to draw the dotted white line
def line2(surf, x):
line = pygame.Surface((2, 20))
line.fill('white')
for i in range(720):
if i % 10 == 0:
surf.blit(line,(x, i*10))
# Define a function to draw the road
def road(screen):
surf = pygame.Surface((300, 720))
surf.fill('black')
screen.blit(surf, (490,0))
running = True
# Start the game loop
while running:
# Set background color
screen.fill('seagreen')
'''
Get pygame events. There is 2 ways to do this.
We can use pygame.event.poll() - return one event or
we can use a loop and get all events. We will use the latter -
pygame.event.get()
'''
# Get keys that are pressed
key = pygame.key.get_pressed()
for event in pygame.event.get():
# A way to exit pygame
if event.type == pygame.QUIT:
running = False
# Can press the esc key and exit the game
if key[pygame.K_ESCAPE]:
running = False
# Blit the road
road(screen)
line(screen, 493)
line(screen, 785)
line2(screen, 640)
# Update the screen
pygame.display.update()
# Set our framerate
clock.tick(fps)
pygame.quit()Which gives us this screen
In the next tutorial we will create the player and mobs
